Invite other students to the lab in order to increase population size. Your student population is a great test population to examine in biology science fair projects.
Use CO2 from Alka Seltzer to knock out flies initially, then place on “ice stage.” Have student lab T.A. maintain fly cultures. Remember to go over ether safety tips when working on fly biology science fair projects.
Borrow electrophoresis equipment. Do demo of electrophoresis. Do simulation of electrophoresis. Use predigested DNA for electrophoresis. Practice your demonstration techniques before helping your students develop their own biology science fair projects.
Use fresh pea seeds. Placing wet, non-germinated peas in vials seems to cause problems with data. To avoid wetting dry peas, determine the mass, volume and hence density of 100 dry seeds (D=M/V). Throw these peas away and then use 25 new, truly dry peas for vial (V=M/D). Use Teflon plumbing tape […]
Use grasses or other outdoor plants for chromatography. Set up numbered bank of tubes (0-10) using serial dilutions of DPIP if Spec 20 is not available. Students then match their tubes to color standards in tube bank. Place spinach in light prior to experiment to activate photosystems. Mix DPIP immediately prior to lab. Borrow Spec […]
Use boiling “pearl” onions from grocery store for root squash. (Onion root squash can be optional). Compare and contrast animal and plant mitosis. Now is a great time to conduct food biology science fair projects experiments as ingredients are on sale for the holiday cooking season.
Obtain catalase from Sigma. May be stored for years in freezer. Use bakers yeast culture as catalase source. Use liver as catalase source. KMnO4 stains may be cleaned up using H2O2. Use syringes to save time (and money) in volume measurements. Find more tips for biology science fair projects by reading news blurbs and […]
Use liquid laundry starch or soluble packing pellets in place of soluble starch. Have students tie knots in the dialysis bags instead of using string. Have each group do each solution in order to minimize class data error. Do not use Glucose test tape as it will always test positive in the presence of IKI. […]
